This invention yrelates to -valveless atom izers and has for its object to provlde an -atomizer in which the bulb itself serves as a container for the liquid so that the atom.

6 izer can be operated with one hand and which operates efficiently as long as any liquid remains in the bulb.

A further object is to provide an atomizer of the type ,above described inwhich com-k plete compiession of thebulb 1s permitted without danger of breaking the liquid tube within the bulb and in which the nozzle may be bent with respect breaking the liquid tube.

A further object is to provide an atomizer in which the bulb serves as a container which will deliver a spray hen held at various angles. -T c A further object is to provide novel means for controlling the discharge of liquid-and air and for causing the air to be so directed into the stream of liquid as to produce a finely divided spray.

A further o ject isl to provide a bulb atomizer in which the liquid is discharged 1n the form of a spray instantly tion of pressure to the bulb and which -requires little elort to operate. c

A further object is t0 rovide an atomizer :o in which the liquid wil not leak from the nozzle when the atomizer is held in inverted position.

A. further object is to provide a novel means for maintaining the end of the liquid se discharge tube in engaging relationship with the interior of the nozzle head.

A further object is to rovide an atomizer which is cheap to manu acture, which is of a form convenient to carry, occupies little 4o s ace, is easy to ill and can be readily c eaned.

Other objects will be ap arent from the following description an accompanying drawings. t l

The following description and accom panying drawings set forth in detail certain means embodying the invention, thel disclosed means, however, constituting but one of the` various mechanical .forms in which :so :the "principle, of the invention may be employed.

Referring to the accompanying drawings to the bulb without upon applica.-

.forming a part of this specication, Fig. 1 1s a longitudinal sectionrthrough the bulb and nozzle; Fig. 2 is a section similar to Fig. 55 1 show1ng the position of the parts when an' or liquid is being drawn into the bulb through the nozzle by expansion of the bulb, the movement of the tubebeing' shown on an exaggerated scale; Fig. 3 is a view showing 60 the nozzle parts and inner tube detached; Fi 4 is a section on line 4-4 of Fig. 1.

eferring to` the accompanying drawings, the atomizer consist/s of an oval shaped bulb 1 of soft rubber which is provided at one 65 end with a supporting base 2 formed by an annular outwardl p and downwardly inclined relativelyt in ange integral with the body of the bulb and a nozzle 3 secured within an opening in the opposite end of the I0 bulb. The soft rubber base ange 2 conforms to the shape of the hand and does not in any Way interfere with the gripping of the bulb and readily. yields when the bulb is compressed. The nozzle 3 has an enlarged 75 inner end 4 adapted to be forced through the openingin the end of the bulband providing an annular shoulder which engages with a shoulder formed on the inner side of the bulb surrounding the opening therein. Theso nozzle is provided with a second `enlarged portion 5 providingA an 'annular shoulder which engages the like shoulder on the bulb surrounding the outer end of the opening therein. The outer enlargement 5 is tapere l 85 inwardly from the shoulder on the outer side thereof and the bulb is formed with an integral collar portion 6 adapted to be stretched over the enlargement 5 whereby the nozzle is more firmly held in place and the sharp edge of the enlargement 5 is covered. Screwed into the outer end of the body portion of the nozzle 3 is a nozzle head 7 which has a bore of slightly less diameter than the bore ofthe body portion of the nozzle and is provided at its outer end with a restricted` opening`8 disposed axially of the bore.

The head 7 ,is slightly tapered to receive an outer removable nose piece 7* which is lon frictionally held thereon so that it can be readily removed to permit insertion of the nozzle into smaller passages, as for instance the nasal passages. The outer end of the nose piece 7 is flush with the outer end of the head 7 so that it does not affect the spray and will not catch liquid falling back from the spray.

For controlling the discharge of air and liquid from the bulb an inner rigid tube 9 is slidably mounted within the nozzle. The inner tube 9 is sageway 1.0 which is adapted to register with the opening 8 in the head of the nozzle. The tube 9 has a square outer end portion 11 which lits slidably within the head 7 of the nozzle so that the ,passageway 10 1s always held in alignment with the 'aperture 8 and providing exterior passageways between the flat side and the lnterior of the head 7. The inner end of the tube 9 projects into the bulb 1 and has attached thereto a iexible rubber tube 12 which is long enough to extend from the inner end of the tube 9'to. the opposite end of the bulb.

The interior of the nozzle head 7 at its outer end tapers inwardly to the central opening 8 forming aconical seat 13 against which the squared end 11 of the Inner tube is ada ted to abut and forming with the s uare end 11 segmental openings through W ich air is directed inwardly into the liquid stream issuing from the passageway 10 breaking up the stream so that it issues from the nozzle in a line spray.

The open end of the flexible tube 12 extends into the liquid within the bulb and serves to normally hold the tube 9 in engagement with the seat 13. Whenever pressure is exerted upon the body of air within the bulb by gripping the bulb, pressure upon the liquid forces the liquid up through the tube 12 and through the small passageway 10 in the tube 9. The air pressure thus exerted upon the body of liquid in the bulb, causes the liquid to flow through the tube 12 and passageway 10, through the discharge aperture 8, and air to flow through the outer passageway and through the segmental openings into the liquid stream, discharging the liquid in a finely divided spray, due to mixture of air and liquid and in a steady stream. When the bulb is released it will gradually expand to its normal shape reducing the air pressure within it and drawing air through the nozzle opening 8. The pressure of the air entering the opening 8 will force the tube 9 away from the opening so that the air can pass freely through the passageway between the tube 9 and the inner wall of the nozzle to the interior of the bulb. The air is thus ermitted to enter the bulb freely so that the ulb will quickly expand to its normal shape. When the wall of the bulb is squeezed inwardly against the tube 12, the tube will readily bend to conform to the inwardly pressed wall and the open end of the tube will remain in the end of the bulb toward ,which the liquid is forced by air pressure provided with an axial passo that the bulb may be tilted to various angles with respect to the vertical while in use.

The bottom of the bulb is preferably rounded so the liquid' contents can be comletely discharged even when the bulb is lield at an angle to the vertical.

The inner open end of the tube 12 is preferably cutV on a bias so that the tube cannot be sealed by engagement of the end thereof with a portion of the bulb. A further advantage of the inner tube arran ment is that it permits the bulb to be hel with the nozzle 1n inverted position without permitting the liquid to leak through the nozzle since when the nozzle is inverted the tube 9 which normally engages the head 7 substantially cuts ofi' communication between the outer passageway and the opening 8.

To fill the bul the bulb is compressed and dipped in the liquid and released. `Upon squeezing and releasing the bulb the desired uantity of liquid will be quickly drawn into t e bulb through the relatively lar e outer passageway between the interior of t e body of the nozzle and the inner tube 9.

To rotect the nozzle and to prevent leakage wien the device -is being carried in a case or in the pocket a soft rubber cap 14 such as shown in F ig. 4 may be secured upon the head 7 of the nozzle.
